I'm sure they would. I believe the SAS was already regarded as a bunch of resistance fighters (terrorists) & not subject to the Geneva Convention for PoWs. Even if they wore uniform, members of the SAS unfortunate enough to be captured were likely to be shot.

..and were often concerned with sexual experiments upon my first Missus....

P.S. recently the camp has been moved elsewhere, so some other poor sod will have a similar problem with his, (ex), Missus...
